it's good earning from signature campaign
for growing your btcoin i prefered you to start altcoin trading, is not eas as you think, and not hard as you think.
if you do it, you will be know when you must buy your altcoin and when you must sell it, last day i can made arround 0.03btc with capital 0.3btc, it's small amount, but if i can continously get profit everyday it's a good amount.
